Grid classes have to be defined with a look-up table and values must match those of the polygon classes for the subsequent comparison. This tool is typically used for a quality assessment of a supervised classification. <hr><h4>Parameters</h4><table border="1" width="100%" valign="top" cellpadding="5" rules="all"><tr><th>Name</th><th>Type</th><th>Identifier</th><th>Description</th><th>Constraints</th></tr>
